I am looking for a guide on how to program for either the Linux or FreeBSD (includes 4.4BSD, NetBSD or OpenBSD) kernel. I would prefer to learn how to write device drivers, but anything would help.
If you know, please email me at *removed* or leave a post here
Regards,
Farhan

I have been reading prep questions for my second unix academy exam, and there's a nuance, I'm not sure I understand it correctly.
I've been under impression from my readings of book by Evi Nemeth and from unix academy DVDs I've been watching, that kernel's modules are drivers. I think of it, as... (25 Replies)
I recently started working with Linux and wrote my first device driver for a hardware chip controlled by a host CPU running Linux 2.6.x kernel.
1. The user space process makes an IOCTL call with pointer to a user memory buffer.
2. The kernel device driver in the big switch-case of IOCTL,... (1 Reply)
I've been researching minimizeing Solaris 8 and found that on the web page http://www.sun.com/bigadmin/content/packagelist/s8u7PkgList/p2.html the package SUNWglmr
is listed as "rasctrl environment monitoring driver for i2c, (Root) (32-bit)" while in the document "Solaris 8 minimize-updt1.pdf"... (1 Reply)
socal(7D) Devices socal(7D)NAME
socal - Serial Optical Controller for Fibre Channel Arbitrated Loop (SOC+) device driver
SYNOPSIS
socal@sbus-slot,0
DESCRIPTION
The Fibre Channel Host Bus Adapter is an SBus card which implements two full duplex Fibre Channel interfaces. Each Fibre Channel interface
can connect to a Fibre Channel Arbitrated Loop (FC-AL).
The socal device driver is a nexus driver and implements portions of the FC-2 and FC-4 layers of FC-AL.
